Piston Rod

In a piston engine, a piston rod joins a piston to a connecting rod.

Many internal combustion engines, and in particular all current automobile engines, do not have true piston rods, and the term piston rod is often used as a synonym for connecting rod in the context of these engines.

All engines with crossheads do have true piston rods. These include most steam locomotives and large marine diesel engines.

Famous quotes containing the word rod:

    “For the first fourteen years for a rod they do whine,
    For the next as a pearl in the world they do shine,
    For the next trim beauty beginneth to swerve,
    For the next matrons or drudges they serve,
    For the next doth crave a staff for a stay,
    For the next a bier to fetch them away.”
    —Thomas Tusser (c. 1520–1580)
